Meet the CIS Team
I received B.E., M.E., and Ph.D. degrees from the University of Tokyo, Tokyo, Japan, in 1976, 1978, and 1988, respectively. With NTT since 1978, I am an NTT Fellow and, presently, Director of NTT Research in the USA. Specifically, I focus on research in cryptography and information security.
In the past, I have served as President of the Japan Society for Industrial and Applied Mathematics (JSIAM), Director of International Association of Cryptology Research(IACR), and as Program Chair of many international conferences. I received the Best and Life-Time Achievement awards from the IEICE, the Distinguished Lecturer award from the IACR, the Purple-Ribbon award from Japanese government, the RSA Conference award and the Asahi award.
OUr cryptography research team
I am a senior scientist at NTT Research and an Associate Professor in the Computer Science Department at CMU. Previously, I was a researcher in the Cryptography and Complexity group at Microsoft Research, India. I received my PhD from the University of California, Los Angeles.
I am broadly interested in all areas of cryptography with a particular focus on the foundations of cryptography. Currently my research topics include secure multi-party computation, non-malleable cryptography, and foundations of blockchains. I am a recipient of several awards such as a JP Morgan faculty fellowship, a 2016 ACM CCS test of time award, a Microsoft Research graduate fellowship, and, a Google outstanding graduate student award. I was also named in the Forbes magazine 30 under 30 list of people changing science and healthcare in 2013.
I am a Senior Scientist at NTT Research and an Associate Professor of Computer Science in the Khoury College of Computer Sciences at Northeastern University. I received my PhD in Computer Science from New York University, and my MS in Computer Science and BS in Mathematics from Stanford University.
My research covers all aspects of modern cryptography, including its theoretical foundations and its applications to information security. My recent research relates to the cryptographic challenges involved in outsourcing data and computation to the cloud; in particular, this includes the construction of homomorphic cryptosystems that allow the cloud to compute on digitally encrypted and signed data while maintaining its privacy and authenticity.
OUr blockchain research team
I am a Senior Scientist at NTT Research. I hold a PhD and MS in Mathematical Sciences from the University of Tokyo, and a BS in Mathematics from the University of Tokyo.
I am presently focused on the digital transformation underway throughout society. Specifically, my research is driven by the idea of “trust” and the creation of dependable digital infrastructures that are accessible to all without barriers. I believe that if new technologies are to fuel our growth, we must first build foundations that are, above all, secure and reliable.
Towards that end, I work extensively in the fields of cryptographic mathematics, software engineering, cybersecurity, and distributed computing. I envision a world where the security of one’s data is considered the norm. In turn, I imagine this same security becoming the cornerstone of our shared technological future. My latest research focuses on the use of blockchain technologies to reimagine how we will work and live in the coming decades. I believe blockchain will be every bit as revolutionary to the world as the creation of the internet, in part because of the insights we uncover at NTT research.
